Cone of a Shasta Red Fir tree, Crater Lake National Park, photo by Robert Mutch

Within the park are represented more than a dozen cone-bearing species—pines, firs, hemlocks, and others—growing in pure bodies or mingled together, forming a confused, broken cover. The few broad-leaf trees that climb this high in the mountains are mostly small and shrubby, forming all underbrush in the open forests and thickets in the moist ground along the streams.

Crater Lake National Park, on account of its position, has the characteristic forest cover of the higher mountains, but within a few hours' ride from any entrance the tree species found are those common in the lower portion of the eastern or western Oregon region [Forests of Crater Lake National Park].
